Commel LS-570 Problems Under QNX 6.4.1   
Platform: 	Commel LS-570
	QNX 6.4.1

Configuration:	2 out of 4 NICs enabled
		gma9xx video driver selected
		PS2 Keyboard & USB Mouse (would like to use usb keyboard but the stability on this platform is not acceptable at this 
point - it was better under QNX 6.3.2)

Problem Description:
Having trouble booting consistently into Photon. More often than not I lose my mouse. In some cases I also lose the 
network and in other cases I get a complete lock-up. I have been trying to diagnose the problem but I have not found 
much to go on. I have tried disabling USB completely and using PS2 kbd & ms but even the PS2 stuff does not work 
reliably. I have tried to increase the verbosity on the devu-[o,e,u]hci.so using -u "-v -dohci pindex=0,verbose=4 -duhci
 pindex=0,verbose=4 "  but I don't get much from them. I increased the verbosity on the network driver (drvnp-e1000.so) 
and I noticed that I got a e1000: unexpected irq cause 0x1 - not sure if this is a problem????

Please help. Is there anything I can do to provide more information? If QNX is listening we sent one of these units to 
you for custom driver development.

Thanks in advance,

- Richard

Follow-up:

CASE1:
1) Enable USB in BIOS
2) Generate network traffic
- on one or more remote nodes execute the following:
find /net/PROBLEM_NODE/usr
3) Machine dies within 10s

Notes:
- Same for i82544 or e1000
- USB and Network share interrupts
- USB triggers a PULSE on interrupt where as Network executes an isr
- i82544 generates massive ammounts of "unexpected interrupt (type 0x1)" slog entries

CASE2:
1) Disable USB in BIOS
2) Generate network traffic
- on one or more remote nodes execute the following:
find /net/PROBLEM_NODE/usr
3) No problems

I could live with CASE2 if my PS2 mouse worked under Photon but it seems it is not functional - any suggestions on how 
to diagnose that problem? hidview sees it?

As a first test can you try the current trunk
io-pkt from the networking project?

In my earlier days I would have loved to download and compile the source but now I am more of an end user. If you could 
supply me with with a binary for the x86 platform I would be happy to try it.

Thanks

Here it is.

Tried the new io-pkt and I still have the same problems.

The system / network hangs when I issue a find /net/LS570/usr from a remote machine and I have USB enabled on the LS570.
 This is repeatable here and QNX has one of these PCs so they should be able to reproduce the same behaviour. 

In the meantime I have disabled USB but the PS/2 mouse is not functional upon initial start of Photon. It seems I have 
to exit to text mode and then relauch Photon to get the PS2 mouse working. I have added the following to the phapps file
 so I don't have to exit:
slay -f devi-hid
devi-hid mouse kbd

I will post the later problem in the appropriate forum.
